EYES ON G-20: World leaders are arriving in Buenos Aires for this week's G-20 summit, where a variety of issues are gaining attention, from trade worries to the presence of Saudi Arabia's Crown Prince Mohammed bin Salman. His possible involvement is under scrutiny in the slaying of Washington Post columnist Jamal Khashoggi.

TRADE WORRIES: Worries remain about pan-Pacific trade tensions, which could hurt Asian economic growth. President Donald Trump told the Wall Street Journal this week he expects to raise tariffs on $200 billion in Chinese imports on Jan. 1. His administration recently imposed a 10 percent tax on those imports, and at the start of the year that's scheduled to rise to 25 percent. Trump has also threatened to place tariffs on all remaining U.S. imports from China.

THE QUOTE: "Traders had been hoping that we would have seen an improved tone between the two powers by now," said Fiona Cincotta, senior market analyst at City Index, about U.S.-China talks. "Any market optimism of easing trade tensions is misplaced."

ENERGY: Benchmark U.S. crude rose 33 cents to $51.80 per barrel. It fell 0.1 percent to $51.56 a barrel in New York Tuesday. Brent crude, the international standard, added 34 cents to $60.74 a barrel.

CURRENCIES: The dollar edged up to 113.80 yen from 113.48 yen late Tuesday in Asia. The euro felt to $1.1292 from $1.1340.
